“Neda” is an entirely a capella tribute to Neda Agha-Soltān, an Iranian woman whose death during the Iranian protests of 2009 became emblematic of the popular struggle there. Kansas-based musician Kawehi put out this well-produced tribute piece, with an appropriately straightforward and conceptually simple video, earlier this year. The clip does include some of the footage of Agha-Soltān’s death, so be warned. If you’re interested in more from Kawehi, check out her thriving Bandcamp page.
